Fusing Jazz into Progressive Rock

I was wondering where I can find more information on jazz theory. I play progressive rock, and I wanted to infuse jazz lines in the solos. Is there anywhere I can look in particular? Or perhaps is there a scale I should grow familiar with to get me going? Any help will be a great help. Thanks!

my dad has played jazz all his life and i have been playin jazz for little while now...two scales that you MUST know: harmonic and melodic minor....also make sure you know all your major scales....lots of dom7th chords and weird inversions....also, with jazz you gotta think "outside the box". meaning, when you are soloing for example, try to play something that complements every chord in your rhythm. hope ive help a bit.....rock on.....
